Identify this antenna?

[Tim Good]

This was on my boat when I bought it, installed high on the rear arch. Never determined what it was for.

Could be anything from Naxtex to wifi.

What does the label say?

It looks like a Glomex product. Maybe a search of the Glomex website might help identify it.

What length is it? You can work out the frequency from that. Likely vhf.

Unless it's a helical inside that glass casing...

Either Navtex or VHF IMO.

Now that you've taken it off, is there something which doesn't work?

At work we have both WiFi and proprietary digital mesh radios that use antennas similar to that.

Not suggesting it's either of those, but the point is that you really can't tell just from the overall appearance.

If we presume there is no system on the boat that does not work with the antenna removed you might look for a coax PL259 connector on the end of a cable not connected to anything that is near the back of VHF set. This could indicate a standby or emergency VHF antenna. ol'will

VHF spare if demasted.

Can’t read it... I can make out “WI**SCH*. Maybe. The letters are really unclear and sun damaged.

Come on PVB you really need to give me more credit ?

I can’t find any coax cable end other than an old Inmarsat C Terminal. I’ll dig around a little more.

There was a cartoonist in Dartmouth some years ago who worked in a curiosity shop. One cartoon of his showed a woman in an obviously new boat with a number of aerials and things stuck on the pushpit talking to another figure. The caption was something like "That one's the GPS. That's the AIS and this is the Navtex and I don't know what the hell this is". Our friends had a new boat that year so we got the cartoonist to put their boat name on the drawing and bought it as a present.

Could be for an AIS system - it's about the right length. However, the same goes for any of the VHF bands.
